Spin–orbit coupling driven electronic phase transition and multifunctional response in lead-free K₂WCl₆ double perovskite for spintronic and energy applications
A comprehensive first-principles study reveals a spin–orbit coupling (SOC)-driven electronic phase transition in the lead-free double perovskite K₂WCl₆. The material exhibits a robust non-relativistic half-metallic ferromagnetic state. The inclusion of SOC strongly reconstructs the electronic states near the Fermi leve...
